, T at whom it WI/LLZ/ concern.-

- Be it known that I, FRANK T. Fancy, a

citizen of the United States, residing at Rochester, in the county .of Monroe and State of New York, have invented new and useful Improvements in Coin-Controlled Dispensing Apparatus, of which the following is a specification. I

My invention relates to coincontrolled vending or dispensing apparatus, and particularly to an-a'pparatus designed for dispensing a spray or small quantity of liquid, such as cologne, upon each successive actuation thereof following the deposit of a prescribed coin.

Theobject of the invention is to provide a vending or dis ensing apparatus of this type which is simpl e of construction, efficient in use, and comparatively inexpensive of-production and which embodies improved means connected by the deposited coin to aprime operating device whereby upon the actuation of such device a definite quantity of the liq- I uid will be delivered;

With this and other, objects in view the invention consists of the features of construction, combination, and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a vending apparatus embodying my invention. Fig. 2 is a fragmentary section through the casing of the same looking toward the rear of the vending or dispensing mechanism. Fig. 3 is a horizontal transverse section through'the vending or dispensing mechani-sm, taken on the line 3 3 of Fig. 2. Figs. 4, 5, and 6 are vertical front-to-rear sections taken on the lines 4 4, 5 5, and 6 6 of Fig. 2. Fig. 7 is a detail view of the pawl or latch and its supporting-bracket. Fig. 8' is asimilar view of the keeper-bar and the contiguous end of the power-transmitting head or plate, and Fig.

necting with an outlet-tube 6, fitted in the front wall of the casing, through which the liquid is dispensed. The storage-reservoir 4- and its discharge-nozzle 5' may be embodied in the form of an ordinary sprayer or vaporizer or may be of any other construction to suit the purpose. Secured upon the interior of the front wall of the casing is a bracket 7, to which is attached one end of a cylinder 8, in which operates a piston 9, the said cylinder and piston constituting an air compressor or supplying devicewhereby air under pressure may be furnished to expel the contents of the reservoir. The educt-ion end of the cylinder is closed and is in communication with the nozzle 5 through a' suitable pipe or conductor 10, while the outer end of the cylinder is open for projection of the piston-stem 11. I

The outer end ofhe stem 1 1 is suitably'se cured to one end of a head or power-transmitting member 12, which is provided at its opposite end with a slot 13, receiving a guideplate 14, formed upon or carried by a bracketi 15, securedto one of the end walls of the easing, whereby the head or plate is'supported and guided in its movements. The said plate or head 12 is also connected to a guide stem 16, which fits and slides in a receiving bore or.

opening 17in a boss 18, formed upon a11d"pro j ecting inwardly from the bracket 7. In the boss 18 is also formed a guide-chamber 19, in which reciprocates a plunger 20, having an outer reduced end 21, disposed in alinem'ent with an opening 22, formed in the head or plate 12 ,the said opening being of a diameter 7.

somewhat smaller than the coin .intendedito be used, so that the deposited coin whenainj serted is brought to lie against the inner side of said plate, will close said opening, and form an abutment against which the reduced end of the plunger may bear to communicate motion to the plate or head 12. The outer end of the boss 18 is formed witha coin-receiving pocket 23 communicating with the outer end of the chamber 19 and with the lower end of the coin-chute 3, said pocket being designed to receive the inserted'coin and support the same in proper relation to the plate or head 12 to prevent the reduced end 21 of the plunger 20 from passing throughthe opening 22, so that when said plunger is moved outwardly it will hold the coin in contact with the head IOO 12, thus enabling the latter to be forced outwardly under pressure therefrom to transmit outward motion to the piston 9, as will be readily understood. The boss 18 is further provided with a longitudinal slot 24, opening through one side thereof and'communicating' with the chamber 19, and through this slot projects an arm 25, extending from the inner or rear end of the plunger 20. The arm 25 is engaged by the hooked free end 26 of a crankarm 27, carried by a rock-shaft 28, journaled in one of the end walls of the casing and a bearing-bracket 29 and provided at its outer end with an operating handle or lever 30, moving in a guide 31, the said shaft and operating-lever constituting a prime operating element for transmitting movement to the head 12, and consequently to the air-compressor 8 9. When the parts are in their normal position, as shown in Fig. 2, and prior to the insertion of a coin, the plunger 20 is free to move through the opening 22 in the head 12, so that the lever 30 may be vibrated and the plunger reciprocated without transmitting motion to the head, and consequently without operating the air-compressor, thus preventing the discharge of fluid from the reservoir 4until a coin of a proper denomination is inserted and feeds into the pocket 23.

The outer or free end of the arm 25 is arranged to move above the flange or plate 14 of the bracket 15, and upon said plate 14 is arranged a spring-plate 32, secured at one end thereto, as shown at 23, and provided at its opposite end with an enlargement or extension 34. The plate 32 is disposed in close relation to the bracket 15 and is of less width than the flange 14, while the enlarged portion 34 thereof is approximately of the same width as the plate 14. The enlarged portion 34 is bent upwardly at an angle, as clearly shown in Figs. 4 and 5, so that when the plunger reciprocates in its casing 19 the outer end of the arm 25, which projects over upon the flange 14 a distance substantially equivalent to the width of the extension 34, moves beneath said extension upon the outstroke of the plunger and then upon the instroke of the plunger rides upwardly upon said extension 34 and depresses the same, the

extension 34 resuming its normal position when the arm reaches the limit of its upward movement by its spring action or resiliency. The said arm 25 and extension 34 of the spring-plate 32 form a trip device for periodically communicating motion to a pivoted latch 35, which is connected by a link or bail loop 36 to the extension 34. The latch 35 is pivoted upon a bracket 37, disposed above the flange 14, and is provided with a pawl 38 to engage a notch or tooth 39 in a keeper-bar 40, slidable in a guide-slot 41, formed in the bracket 37, and connected at its outer end to the head 12.

When the plunger 20 moves outwardly and engages a coin A, inserted in the pocket 23, and communicates motion to the head 12, the keeper-bar 40 will slide outwardly with the head, and when the latter reaches the limit of its outward movement the pawl 38 will engage the tooth or notch 39 ,and thus lock said bar and head against inward movement or retraction while the plunger is returning to its normal position, thus permitting the plunger to move away from and release the coin A, which thereupon drops down to the bottom of the casing or into a suitable cham ber provided for its reception. The outward movement of the head 12 is resisted by retraction-springs 42, connected thereto and to the bracket 7, and rearward movement of the rock-shaft 28 and lever 30 is similarly resisted by a retracting sprii'ig 43, connected at one end to the casing and at the other end to an arm 44, projecting from said shaft, and the action of the pawl 38 in engaging the notch 39 of the bar 40 is to resist the retraction of the head 12 under the action of the springs 42 until the plunger 20 has moved rearmtrdly or been retracted to a predetermined extent, sufficient at least to release the coin A, the retraction of the plunger, its acting rockshaft, and the lever for operating said shaft being, however, permitted, as the retraetiwv action of these parts is not regulated by said pawl. As the plunger nears the limit of its inward or retractive movement the projecting end of the arm 25 connected thereto rides upon the inclined portion or extension 34 of the plate 32 and depresses the same, thereby drawing down upon the connection 36 to swing the latch and retract the pawl 38, thus permitting the springs 42 to return the head and its coacting parts for further operation.

It will thus be understood that when the lever 30 is moved reaiwvardly and imparts rearward motion to the rock-shaft 28 the arm 27 will transfer motion to the arm 25 of the plunger 20, and if a coin has been illserted in the slot 2 and passed through the chute 3 to the pocket 23 the reduced end 21 of said plunger will engage said coin and transmit motion to the head 12. On this outward motion of the plunger and head the extended end of the arm 25 moves under the trip-spring 34, and consequently does not engage said spring, while the outward. movement of the head 12 transmits motion to the piston 9, which is forced outwardly within the cylinder 8. hen the parts reach the limit of their outward movement and the extended end of the arm has passed the lower end of the spring-trip 34, the pawl 38 engages the notch 39 in the bar 40 and locks the head 12 against rearward movement. The plunger 20 upon it being retracted by the ac tion of the spring 43 and return movement of the shaft 28 and handle 30 releases the coin A, which drops down into the bottom of the casing, and upon the continued inward m over ment of the plungerthe extended end of the arm 25 rides up on the spring-trip 34 and depresses the same to disengage the pawl and permit the parts to return to their normal positions, as above described. The inward movement of the head 12 I causes-the plunger.

Q toibe forced back on its returnstroke in the cylinder 8 and to force the air previously taken into said cylinder through the pipe or connection 10 into the reservoir 4, the charge of air supplied to said reservoir -forcing a por- .tion of the liquid contained therein out through the nozzle 5,and discharge-tube :6.

' From the foregoing description, taken in connection with the accompanying drawings, the construction andmode of operation of the invention will be understood without a further extended description.

Changes in the form, proportions, and minor details of construction may be made within the scope of the invention without departing from the spirit or'sacrificing any of tractive movement to release the coin, a.

spring-retracted trip member, an operating connection between the pawl and trlp member, a projection upon the plunger adapted to use W bracket carried by the casing, a supportingoperate sald'trip member, and springs for retracting the plunger and head.
